Previous practice was to upload the zips to a server located in the region under investigation - NZ, in this case. The kick might be better directed there...Thanks for the hint Andy. zips now uploading. ID: 65537 ·  |

I now have three N216 work units running. IIRC, they trickle every 1/8 of the time through. It appears I do not remember correctly. These work units give 4 or 5 trickles, each about 25% apart. So about one every two days on my machine.

These work units give 4 or 5 trickles, each about 25% apart. I am just at 25% and see only one trickle too. Running four at a time, they are taking over 13 1/2 days on a Ryzen 3900X, but that is with all cores loaded. When I ran them on a Ryzen 3600 with only six cores (50%) in use, they would take a little under 10 days. So I think the ratio is right for virtual cores. ID: 65539 · |

These work units give 4 or 5 trickles, each about 25% apart. The _5_ in the task name just before the batch number is the clue here. It means they are five month tasks which will send trickles at each 20% or shortly after except for 5.zip which for some reason is produced a bit before the task reaches 100%. ID: 65540 · |

Running four at a time, they are taking over 13 1/2 days on a Ryzen 3900X, but that is with all cores loaded. On my machine, they take about 8 days. using 8 of the 16 cores of my machine. I limit my machine to a maximum of 4 cores for ClimatePrediction work units, and at the moment the other 4 cores are doing MilkyWay.

If you're on Intel/Linux, https://github.com/opcm/pcm will get you much more detailed stats on cache behavior (per core), global memory bandwidth, instructions retired, etc. ID: 65542 · |

Oh, I just build it from source. As long as it's got MSR access (modprobe msr), it should work fine. ID: 65544 · |

Don't get tasks this PC https://www.cpdn.org/show_host_detail.php?hostid=1521336 on VirtualBox got six tasks N216, but this PC https://www.cpdn.org/show_host_detail.php?hostid=1532298 on WSL2 won't get tasks sidock@home is running, so there is no basically problem. Any idea? ID: 65546 · |

Don't get tasks Nothing obvious looking at the link for the machine. One thing to remember is, not to keep clicking the update button because once an attempt has been made to get work, there is a back off time of one hour before another attempt can be made. Could you post from the event log what shows up after you request work? That might give some clues. ID: 65547 · |

Double check your basic "Computing preferences" settings, like work cache, CPU usage, and others. Try turning on sched_op_debug and work_fetch_debug in "Event Log options" before requesting work again. Check the Event Log afterwards to see if any new clues show up. I use WSL2 also, although 20.04, and have no problems getting work. ID: 65550 · |

Don't get tasks Try suspending any other running projects and increase number of days of work to 10. ID: 65553 · |

Try suspending any other running projects and increase number of days of work to 10. I have my days work set to 0,25 minimum and 2 days additional. I have no difficulty getting CPDN work units, when they are available for my machine and OS. For CPDN, I do not turn off other BOINC processes just to get work units. ID: 1511241

bibi What we need to see is from near the start of the Event log.

Have you checked your account on this website, to ensure that your preferences include N216 for the venue that host is using? (I am not having any problems.) But I do not think it is possible in preferences to select the tasks the machine uses anymore. It was possible years ago. Where would I do this if I wanted to? (I see no need to do this at this time.)

It would normally be on https://www.cpdn.org/prefs.php?subset=project, but I see it's been taken away. The setting that caused me grief of a similar nature was no_alt_platform in the cc_config.xml file. With this set on the system worked fine with all other projects but would not download any CPDN WUs. ID: 65562 · |
